配置使用spring来管理sessionFactory。

这个配置需要在applicationContext.xml中来配置

解决方案：

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="configLocation">
<value>classpath:cn/tzm/springhibernate/transaction/config/hibernate.cfg.xml</value>
</property>
</bean>

报错：
